Improvement in straw-cutter



BERNHARD SUVERKRUP, OF LOUISVILLE, KENTUCKY.

IMPROVEMENT IN STRAW-CUTTER.

Specification forming part of Letters Patent N o. 72,936, dated December 31, 1867.

To all 'whom 'it may concern:

Be itknown thatI, BERNHARD SUVERKRUP, of the city of Louisville, county of Jefferson and State of Kentucky, have invented a new and useful Improvement in Cutting-Boxes,

entitled Bernhard Suverkrups Improvement in Cutting-Boxes#7 and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the machine, as will be seen by reference to the annexed drawings, making part of this specification, in which- Figure l is a perspective View of the mai chine. Fig. 2 is a front view of the wheels of the machine, showing` the arrangement of the feeding-fixtures.

Q is the box of the machine, made of Wood, an d in which the straw is placed in order to be cut, H, arm. G are the two miter-wheels which drive the machine by turning the crank S, by which motion is given to the ily-wheel A, on which the knife B is attached, and as the flywheel revolves the knife passes around against the face of the cutting-box, which is faced with iron orl steel, and cuts the strawor other material the same as if cut with shears, and is fed by the straw being forced out at the front of the machine by two rollers inside of the box Q, which rollers are driven by the wheels E and F, Fig. 2 showing the feed arrangement.

O is the slot in the bevel-wheel H,in which is tted a small wrist that is made adjustable, in order to lengthen or shorten the length of the material to be out. This wrist gives m0- tion to the levers K and L, to which it is attached, said levers having a joint in them at U, and when vibrated by the wrist P the ratchet M is drawn back by the levers L, and when pressed forward again it turns the wheel F forward, which is attached to the rollers in` side the machine, and in order to keep it from turning back again is caught by the springcatch N, and is held fast until the fly-wheel A revolves again, and as the 'ratchet turns the wheels E and F the rollers inside the boX are turned and feed the machine.

The above is a full and clear description of the machine, and is operated by placing strawI or other material in the box Q and pressing it up to the rollers so that they may receive it, and then turning theshaft by the crank S, which gives motion to the flywheel and knife, which, when passing around, cuts the strawor other material. Said knife is so arranged as to be easily adjusted by two bolts which hold it to the wheel, having two nuts near each end, which can be adjusted at pleasure, and also a set-screw against the outside of the knife, at the outer end, to prevent it from springing olf when hard pressed by the feed or otherwise.

I do not claim anything in the original construction of the above machine, but

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination of the crank S, fly-wheel A, with adjustable knife B, bevel-wheels E, F, G, and H, slot O, wrist I), levers K and L, ratchet M, and spring-catch N, when constructed, arranged, and operating in the manner and for the purposes set forth.

BERNHARD SUVERKRUP.
